Question

Which of the following statements is INCORRECT in case of Hofmann bromamide degradation ? (A) Reaction is useful for decreasing length of carbon chain by one carbon atom (B) It gives tertiary amine (C) It gives primary amine (D) Aqueous or alcoholic KOH is used with bromine

Tardigrade Admin · Accepted Answer

The statement (B), 'It gives tertiary amine' is an incorrect statement. The correct statement is, 'It gives primary amine'. R - CONH 2+ Br 2+4 NaOH arrow R - NH 2+ Na 2 CO 3+2 NaBr +2 H 2 O

Q. Which of the following statements is INCORRECT in case of Hofmann bromamide degradation ?

Reaction is useful for decreasing length of carbon chain by one carbon atom

It gives tertiary amine

It gives primary amine

Aqueous or alcoholic $K O H$ is used with bromine

The statement (B), 'It gives tertiary amine' is an incorrect statement.
The correct statement is, 'It gives primary amine'.
$R - CON H_{2} + B r_{2} + 4 N a O H \to R - N H_{2} + N a_{2} C O_{3} + 2 N a B r + 2 H_{2} O$
